FIELD OF THE INVENTION

The present invention relates to the field of computer software. More specifically, the present invention relates to the integrated deployment of software projects to remote computers.

BACKGROUND OF THE INVENTION

Currently, it is common for large numbers of mobile workers who perform tasks in the field to record their work-product on paper-based forms. Subsequently, they return these forms to a central office where clerical personnel manually enter the data into a company database. This process, however, is error-prone and creates unnecessary delays in dissemination of business-critical information from the field to the business management. With the advent of mobile computers such as laptops, tablets, and PDAs, a quantum leap in efficiency can be achieved by having mobile workers record their data on handheld devices which can synchronize this information directly into the business database via a wired or wireless connection. This eliminates all transcription errors associated with paper forms and greatly speeds the flow of business information to the decision makers.

In order to capitalize on the business promise of handheld devices, firms need applications built specifically for mobile workers. These applications are unique because they must integrate data from across the entire business enterprise as well as from third parties such as suppliers and partners in a coherent work environment tuned for a company's mobile workforce.

Application development tools and infrastructure are commonplace, but these require costly and time-consuming development to create lines of business applications. Moreover, such business solutions tend to be costly and inflexible, requiring expensive and time-consuming custom development when business processes require an application to be changed. As business processes evolve, the mobile software applications supporting those enterprises must be easy to change and deploy to mobile workers “on the fly”.

Typical mobile software deployment platforms, however, suffer from several drawbacks. Many were designed with desktop (i.e., non-mobile) devices in mind. While they still can function in the mobile world, they do not take into account many of the unique features of mobile computers, such as the increased use of different operating systems, or the possibility of frequent network dropouts. Furthermore, they are typically designed such that an administrator needs programming or information technology skills in order to set up distribution of updates, as hard coded implementations are standard in this field.

Additionally, software development platforms typically utilize relational databases for storage. A relational database stores data in a number of disparate tables, each of which is linked or related to another table. A table is organized by rows and columns, each row or record containing the same columns or fields. A conventional flat-file database would store all the data in a single table, but the relational model allows for maximum flexibility for querying the data. Data need only be brought together for a particular query, so the structure of the database contains no assumptions about what sort of queries may be required in the future. Another powerful feature of the relational model is that each data item appears only in a single place in the tables and thus only needs to be updated in one place when it changes.

In the relational model, each table has a primary key, which is a field or combination of fields that uniquely identifies each record in the table. The primary key provides a means to distinguish one record from all others in the table.

When a field in one table matches the primary key (or a candidate key) of another table, the field is referred to as a foreign key. The foreign key is the anchor on the many side of a one-to-many or many-to-many relationship, much as the primary or candidate key is the anchor on the one side of this relationship. A foreign key is a linchpin used to ensure that invalid data is not entered into a table. It also prevents a user from deleting or updating in a way that might leave orphan rows.

There are several different classes of relationships possible using a relational model. The first is a one-to-one relationship. Two tables are related in a one-to-one relationship if, for every row in the first table, there is at most one row in a second table. True one-to-one relationships seldom occur in the real world. This type of relationship is often created to get around some limitation of the database management software rather than to model a real-world situation. For example, one-to-one relationships may be necessary in a database when there is a need to split a table into two or more tables because of security or performance concerns. Tables that are related in a one-to-one relationship share the same primary key.

A second type of relationship is a one-to-many relationship. Two tables are related in a one-to-many relationship if, for every row in a first table, there can be zero, one, or many rows in a second table, but for every row in the second table there is exactly one row in the first table. The one-to-many relationship is also referred to as a parent-child or master-detail relationship.

A third type of relationship is a many-to-many relationship. Two tables are related in a many-to-many relationship when, for every row in a first table, there can be many rows in the second table, and for every row in the second table, there can be many rows in the first table. Many-to-many relationships can't be directly modeled in the typical relational database, and therefore these types of relationships must be broken into multiple one-to-many relationships. A third table, known as a linking table, may then be utilized to model the relationships between the two tables.

Regardless of the type of relationship used, past relational models utilized foreign keys for the “many” side of the relationship (except for one-to-one of course). These foreign keys, however, must be constantly managed to ensure that no errors occur in the storage of the data. This wastes both computing power and memory space. Additionally, the traditional heavy-weight dependence on foreign key relationships causes tables to have database enforced key constraints, which limits the ability of a user to easily add new tables or permutations.

What is needed is a solution that overcomes the limitations of prior solutions.

DETAILED DESCRIPTION

Embodiments of the present invention are described herein in the context of a system of computers, servers, and software. Those of ordinary skill in the art will realize that the following detailed description of the present invention is illustrative only and is not intended to be in any way limiting. Other embodiments of the present invention will readily suggest themselves to such skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations of the present invention as illustrated in the accompanying drawings. The same reference indicators will be used throughout the drawings and the following detailed description to refer to the same or like parts.

In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with application- and business-related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.

In accordance with the present invention, the components, process steps, and/or data structures may be implemented using various types of operating systems, computing platforms, computer programs, and/or general purpose machines. In addition, those of ordinary skill in the art will recognize that devices of a less general purpose nature, such as hardwired devices, field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), or the like, may also be used without departing from the scope and spirit of the inventive concepts disclosed herein.

The present invention provides a single integrated software project deployment platform that allows administrators to easily and effectively deploy software projects to remote computers. This allows business users with no Information Technology background or capabilities to develop and deploy sophisticated applications for execution on remote systems, such as mobile computers. Mobile workers can connect to backend enterprise systems in real-time to capture rich data types such as digital signatures, photos, speech recognition, bar code scans, etc. while in the field.

It should be noted that while the applicability of the present invention to mobile computing will be described throughout this document, the present invention should not be limited to the deployment of projects to mobile computers. Many of the elements of the present invention could apply more generally to any type of computers.

FIG. 1 is a block diagram illustrating an architecture for integrated deployment of software projects in accordance with an embodiment of the present invention. Each element in this architecture may be embodied in software, hardware, or any combination thereof. A remote computer such as a mobile device 100 may contain client software 102 and a local database 104. The client software 102 may include a Business Rules Runtime Engine 106 and a database access engine 108. The Business Rules Runtime Engine 106 may interpret application logic received from a central server and render a user interface for the application logic based on the platform and language of the mobile device 100. The Business Rules Runtime Engine 106 may also receive and execute automatic updates to various plug-ins and system software on the client software 102, as well as automatically discover appropriate device drivers. The database access engine 108 may interface with the Business Rules Runtime Engine 106 to provide disconnected, connected, or hybrid data access to the local database 104 and/or central database 110.

A central server 112 may contain server software 114. The central server 112 may also contain a central database 110, however in many implementations it will be more desirable to locate the central database 110 outside of the central server 112. The server software 114 may include a synchronization module 116 and an administration tool 118. The synchronization module 116 may utilize a synchronization web service 120 to coordinate the synchronization of projects, applications, plug-ins, and system updates and perform communication hub messaging. A monitor 122 may monitor the system and automatically configure it to improve efficiency. Access to the central database 110 may be facilitated through a database access engine 124.

The administration tool 118 may include an administration engine 126 and a database access engine 128. The administration engine 126 may provide point and click authoring of applications and workflow, deployment management, enterprise data authoring, user administration, plug-in management, project management, results viewing and reporting, enterprise data management, Lightweight Directory Access Protocol (LDAP) Integration, and definition of an extensible workflow/device model. Access to the central database 110 may be facilitated through the database access engine 128.

The central database 110 may provide for support of local, external, compound, or other types of data objects. However, many types of database implementations are possible in accordance with the present invention, and thus this should not be read as limiting.

A business administrator may create a software project using the administration tool 118. Projects may include software applications (also known as tasks) as well as workflow. Each application may comprise a series of data gathering “steps”. A step may contain information regarding the onscreen prompt for the data, the type of data expected (e.g., text, date/time, barcode, photograph) and the type of input mechanism to capture the data (e.g., textbox, calendar, barcode scanner, camera). Steps that capture rich data types requiring external devices need not prompt for device specific information such as hardware settings. Any device that supports the rich data type may be automatically discovered and used on the client using automatic device driver discovery. Steps may also contain options for defining valid lists of values, minimum, and maximum values, formatting of the onscreen data, translation of onscreen values to database values, and data present requirements. By default the order in which the steps are provided by the business administrator will be the order they are presented to the user. A step may also optionally contain workflow. Workflow will be described in more detail later, but it can be fired during step validation or after the value has been accepted into the step.

These steps may then be stored in the central database along with their attributes and then synchronized with the client software. On the client software side, the user interface could be automatically rendered or the administrator can design custom screens. Automatic rendering of a user interface will be described in more detail below.

Authoring of the application may be performed by the business administrator using a point and click interface. This is depicted in FIGS. 2-5. FIG. 2 is a diagram illustrating a screen capture of adding a step in accordance with an embodiment of the present invention. First, the business administrator may click an add step button 200 using a mouse or by pressing enter while the add step button 200 has focus. FIG. 3 is a diagram illustrating a screen capture of a step prompt in accordance with an embodiment of the present invention. The business administrator is presented with a means to enter a prompt for the step 300, enter the data type expected 302, and enter an input mechanism 304 for the data. The business administrator may then optionally edit workflow for the step or set various step options including the steps name, default value, range of numeric values or string lengths allowed, lists, and format, as depicted in FIG. 4. FIG. 4 is a diagram illustrating a screen capture of editing workflow in accordance with an embodiment of the present invention. The business administrator may also define various options, such as valid lists of values, minimum, and maximum values, formatting of the onscreen data, translation of onscreen values to database values, and data present requirements, as depicted in FIG. 5. FIG. 5 is a diagram illustrating a screen capture of adding options in accordance with an embodiment of the present invention. The business administrator may then complete the addition of the step to the application by pressing OK 500. The screen may then return to that as depicted by FIG. 2, and focus may then be put back on the add step button 200 so that steps can continue to bed added quickly without using a mouse.

Workflow may also be authored using a point and click interface. Each step can contain an unlimited series of workflow elements that will fire when the step is validating the input from the user or after the step has accepted the value. Each workflow element may be configured via an onscreen wizard without coding or compiling. The workflow may be authored on an individual step or on the application, and can also be authored for server side functionality. Workflow may also be rearranged using the point and click interface and new workflow can be inserted or added.

In accordance with an embodiment of the present invention, an extensible workflow model may be provided. The workflow function may be built upon a defined standardized interface. Implementing a class with this interface will make it available as a workflow. A workflow function or series of workflow functions can be compiled into a single workflow file (e.g., *.dll). Upon startup, the user device may look for these *.dll files and instantiate an instance of the function class. If a task uses the workflow in one of the *.dll's, the instantiated object may be called to perform the function. Any workflow function files loaded as plugins to the system may be automatically distributed to the mobile clients and available locally for authoring. Workflow functions can be optionally licensed, preventing use without payment for the function(s).

In accordance with an embodiment of the present invention, automatic device driver discovery may be provided. For steps that capture rich data types from external devices such as barcode scanners, magnetic stripe readers, and cameras, the system may automatically attempt to find the appropriate driver for the platform and device. A device driver may be built upon a standardized interface. Implementing a class with this interface will make it available as a device for input (or output). A device driver or series of drivers can be compiled into a single driver file (e.g., *.dll). Any device drivers loaded as plugins to the system may be automatically distributed to the mobile clients and available locally. Device drivers can be optionally licensed preventing use without payment for the drivers. Device drivers can be created to support any type of device imaginable, including barcode scanners, magnetic stripe readers, cameras, file attachments, sketches, digital signatures, biometric capture devices, RFID devices, and printers.

After deployment of the project to the mobile computer, the client software may run the application using the Business Rules Runtime Engine. This Engine may be available for all platforms and ensure consistency between the runtime environments. Applications can then run and collect data within the local database to provide for disconnected access to the application (by default). Applications can also optionally request data to a connected live server (connected or hybrid). As input into steps is received, a workflow may fire and be run. Any workflow that requires an immediate connection back to the central server data may have the request brokered to the database engine for processing. If a step contains a rich data type, the appropriate device driver for the platform and device is selected if available.

The Synchronization Module may pass data objects with encoded structured methods, logic, and workflow to be interpreted, displayed, and enforced on the mobile computing device. The mobile computing device then interprets the data object's actionable state, displays a user interface, manages business data, method, logic, and workflow and creates results (in the form of results objects). These results objects may contain an abstraction of the data captured on the mobile device in response to requests by the data object's embedded business processes. The results objects mat then be transferred back to the server and used for display, reporting, and driving diverse enterprise applications.

Applications that are run can be put on hold for completion later, and multiple applications may run simultaneously, subject to the processing power and memory availability of the mobile computer. Furthermore, application definitions may be cached for efficiency in rerunning the same application. The screen layout to use for the application may be determined using intelligent rendering, which will be described in more detail later. If there is a matching screen layout for the platform and language, it may be used. If there is a matching screen layout for the platform, but not the language, a default (e.g., English) may be used. If there is neither a machine layout for the platform or the language, one will be automatically generated in English for the current platform using intelligent rendering.

Each step captured may be time stamped with the collection date for the step, for later use. Each application instance may receive a unique identification to ensure its uniqueness system-wide. Any completed applications may have their results stored in the local database. Completed applications may then synchronize with the server to provide the results.

Enterprise data may be object-oriented. It can exist locally, externally, or virtually. Any object instance can be related to any other object instance. Enterprise data may be used in projects to define a subset of the information available to an application running on the mobile device. The central enterprise data may then optionally be queried remotely from the application in the field.

Projects comprise one or more tasks, the users they should be deployed to, and/or any enterprise data used by the tasks. Projects may also comprise scheduling options that determine when to deploy or rescind the project and its applications and data. These events occur whether the administration tool is running or not. Results of the applications that have been synchronized with the server can then be viewed by the business administrator per project or per task, using the administration tool. The results may also be exported into third party applications such as spreadsheet programs or word processors. Statistics regarding the deployment may also be available, on a per user, per application, or per project basis.

In an embodiment of the present invention, changes to a project may be automatically synchronized to the client software to allow for on-the-fly deployments of changes to applications or workflows. The updates may be integrated into projects immediately upon synchronization, regardless of whether the project is currently running or not. This creates a bi-directional data flow between the business administrators and the mobile workers that exists for the life of the project. Additionally, smart synchronization features may be provided that intelligently synchronize the information and monitor the features and attributes.

Smart synchronization may synchronize or remove projects based on deployment configuration. It may send all data associated or needed by a project automatically, and remember what data was sent to avoid redundancy and decrease synchronization times. Data sent for expired projects may be automatically cleaned up on the mobile device. Any plug-ins (e.g., workflow functions or new device drivers) may be automatically distributed to the correct device. Additionally, any system or software updates (such as new features or bug fixes) may also be automatically distributed to the correct device and set up for automatic installation. This also includes database updates. In an embodiment of the present invention, while the database schema is identical between the database and the client, only project and enterprise data relating to the current mobile worker's currently active projects is downloaded to the mobile device during synchronization.

In an embodiment of the present invention, a proprietary binary format may be used in communication payloads which yields better efficiency, security, and footprint. This proprietary format may include only bytes of serialized objects along with object types. By storing these serialized objects in binary form, the overhead of XML or other languages can be avoided and the total number of byes in the entire transmission is much smaller.

Smart Synchronization may automatically occur whenever an IP address is present (e.g., devices is cradled, on an 802.11 network, on a GPRS network, or connected via a network card or modem). This allows mobile devices to be updated in a manner that ensures as best as possible that projects on the mobile devices are the latest versions of the projects. Intelligent caching of data on the server may be performed to maximize scalability and throughput. Smart synchronization may also act as a scheduler for projects set up by an administration tool. Smart synchronization may also log its synchronization activities and provide multiple levels of log detail for administrators to view.

Additionally, Smart Synchronization may act as a liaison for remote access to the central database by mobile devices requesting access to live data. It may also act as a communications hub for any messaging between the mobile devices and/or the central administrators.

In an embodiment of the present invention, smart synchronization may include continuous delta synchronization. Here, the changes to enterprise data, system files, projects, tasks, metadata, etc. are proliferated to the client devices during synchronization. This provides for on-the-fly changes to be made and realized in the field. When a project expires or is canceled, the project and all of its related data may be automatically removed from the clients during the next synchronization. If desired, the synchronization records for a device or user can be reset, causing a full re-send of all data appropriate for that user and device.

FIG. 6 is a flow diagram illustrating continuous delta synchronization in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. A system table may contain all items that need to be synchronized for a particular device and user. Additionally, objects, including administrator-defined or system objects, may have system fields that designate the last time that object was changed and who changed it. It should be noted that deletion of an item may also be considered a change. At 600, the monitor may continually assess changes to all data in the system. At 602, it may be determined if a new change is discovered. If so, then at 604, the monitor may make appropriate entries into the synchronization system table for the device and user expected to get those changes. At 606, the synchronization server may create a manifest of all items to synchronize to the client device. This may be created based on information in the synchronization system table. It may be created upon receipt of a synchronization request from the mobile computing device, which may be generated upon the detection a network address for the mobile computing device by the synchronization server. In order for an item to be included in the manifest, it should pass the following tests:

-   -   1. The user should be a current valid user     -   2. The device should be a current valid device     -   3. The item should be designated to go to the requestor     -   4. The item should be designated as not yet received by the         requestor     -   5. The item should have a retry count below a set number if not         received by the requestor. This set number is configurable.

At 608, the client may request an item from the synchronization server. At 610, the synchronization server may loop through all the items in the manifest and send them to the client in groups. The size of the group is configurable. At 612, the server may increment a retry count on each of the sent items' synchronization status in the synchronization system table.

At 614, the client may then save the items to the local database. At 616, the client may send a confirmation back to the server that the items were successfully saved. If the client sees that it already has the most recent version of an item, it may simply confirm the item without requesting it. At 618, when the server receives a confirmation request, it may mark the item as synchronized for that requestor in the synchronization system table. If an error occurs on the client during processing, the error information may be sent to the synchronization server for logging on the server. The log may include the user, device, and timestamp information. Server side synchronization errors may also be logged.

FIG. 7 is a block diagram illustrating an apparatus for intelligently synchronizing a central server with a mobile computing device in accordance with an embodiment of the present invention. Each element in this apparatus may be embodied in software, hardware, or any combination thereof. A data change continuous monitor 700 may continuously monitor changes to data in the central server. A synchronization system table change recorder 702 coupled to the data change continuous monitor 700 may, upon discovery of a change relevant to the mobile computing device, note the change in a synchronization system table corresponding to the mobile computing device, the synchronization system table containing all items that need to be synchronized for the mobile computing device. A synchronization manifest creator 704 coupled to the synchronization system table change recorder 702 may create a manifest of all items to synchronize with the mobile computing device, the creating based upon information in the synchronization system table. The synchronization manifest creator 704 may include a series of components designed to ensure that only the proper items be added to the manifest. This includes a non-current or valid user item excluder 706 which excludes an item from the manifest if the item corresponds to a user who is not a current valid user. A non-current or valid mobile computing device item excluder 708 may exclude an item from the manifest if the item corresponds to a mobile computing device that is not a current valid mobile computing device. A non-mobile computing device destination item excluder 710 may exclude an item from the manifest if the item is not designated to go to the mobile computing device. A received item excluder 712 may exclude an item from the manifest if the item has been designated as received by the mobile computing device. Finally, a retry limit exceeded item excluder 714 may exclude an item from the manifest if the item has an associated retry count equal to or greater than a preconfigured retry limit.

A manifest item mobile computing device item transmitter 716 coupled to the synchronization manifest creator 704 may transmit the items in the manifest to the mobile computing device. This may including transmitting the items in groups by continuously looping through the manifest using an item grouper 718. A synchronization system table retry count incrementer 720 coupled to the manifest item mobile computing device item transmitter 716 and to the synchronization system table change recorder 702 may increment a retry count in the synchronization system table for each transmitted item. A transmitted item mobile computing device confirmation request receiver 722 may receive a confirmation request from the mobile computing device for one or more transmitted items. Finally, a synchronization system table confirmation request marker 724 coupled to the transmitted item mobile computing device confirmation request receiver 722 and to the synchronization system table change recorder 702 may mark each of the one or more transmitted items for which a confirmation request has been received as synchronized in the synchronization system table.

The synchronization server supports the ability to proxy database requests to its database. Requests for remote access may be made via known web service calls by the database access engine. FIG. 8 is a flow diagram illustrating handling a remote access request in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 800, when a database request is made to the database access engine, the database access engine determines if the request should be routed to the server or performed locally. If it is to be routed to the server, then at 802 a raw database call (such as a SQL call) may be sent to the synchronization server for application to the database. If not, then at 804, records corresponding to the database request may be retrieved locally. At 806, any records returned or retrieved may be converted to a proprietary database access engine record format. At 808, the database access engine may return the records to the caller. Any returned records may be converted to an internal proprietary record format similar to that utilized for communications as described above. Namely, the records may be serialized and stored in binary form for transmission as opposed to using a web language such as XML, which adds overhead.

The synchronization server supports the ability to receive or send communication requests to other users or administrators of the server. Requests for pending messages and requests to send messages may be made via known web service calls. Messages may be stored in a proprietary format that supports the ability to send partially complete tasks to other users, messages, attachments, etc. This proprietary format may be similar to that utilized for communications as described above. Namely, the communications may be serialized and stored in binary form for transmission as opposed to using a web language such as XML, which adds overhead.

Messages may be stored in a system table. FIG. 9 is a flow diagram illustrating handling a request for pending messages in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 900, when a request is received, all messages targeted for that user may be retrieved from the database and sent back. At 902, if the user has been designated to integrate with another servers, such as a Microsoft Exchange server, any pending messages in their exchange account may be converted to the proprietary format and sent. At 904, the messages may then be saved in a local data store where they can be retrieved at will.

FIG. 10 is a flow diagram illustrating handling a request to send a message in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 1000, when the request is received, all recipients may have an entry made for the message in the messaging system table. At 1002, if the user has been designate to integrate to Microsoft Exchange, their user account may have a message sent to it from the server containing the same content as the message in standard email form. An administration tool may be provided to allow for authoring and central management of applications. Through it, projects and deployments may be created, configured, and managed. Additionally, statistics can be viewed regarding deployments. Reports of results coming in from deployed applications may also be viewed. The administration tool may also provide for the management of plug-ins and system updates, as well as the creation, configuration, exploration, import/export, and management of enterprise data, and user administration, including security and LDAP integration, as well as license administration.

In an embodiment of the present invention, intelligent rendering may be utilized to create content to places on a screen according to various aspects of the device on which it is to be rendered. Therefore, for example, the system may automatically create a screen set appropriate for a PocketPC device or a Windows device. The Administrator may override this by creating a custom screen.

On PocketPCs, screens may be created in a linear fashion and paginated so that scroll bars are unnecessary. As such, it may be necessary to split the information over two or more pages. FIG. 11 is a diagram illustrating an example of a screen automatically rendered on a PocketPC device in accordance with an embodiment of the present invention. FIG. 12 is a flow diagram illustrating a method for automatically rendering a PocketPC screen in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 1200, a page may be created based on a default size for the device, with each step positioned from top to bottom. The default size may be set by the administrator. At 1202, any multiple line steps may have their height increased to accommodate multiple lines. At 1204, if the bottom of the page is reached, a new page may be created and the process may continue from the top of the new page. At 1206, once the last step is reached, the screen may be considered finished.

On TabletPC or Windows devices, the screens may be generated in a resizable format so that scroll bars are unnecessary. FIG. 13 is a diagram illustrating an example of screen automatically rendered on a TabletPC/Windows screen in accordance with an embodiment of the present invention. FIG. 14 is a flow diagram illustrating a method for automatically rendering a TabletPC/Windows screen in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 1400, a page may be created based on a default size for the device, with each step positioned from top to bottom. The default size may be set by the administrator. At 1402, each step may be set to resize horizontally with the screen. At 1404, any multiple line steps may have their height increased to accommodate multiple lines. At 1406, if the bottom of the page is reached, a new page may be created and the process may continue from the top of the new page. At 1408, once the last step is reached, the screen may be considered finished.

For all platforms, a default TabletPC/Windows and PocketPC layout may be created in English. The system also allows for customized screens which provide the following feature set:

-   -   1. Steps can be positioned anywhere     -   2. Steps can be sized to any size     -   3. Steps can be anchored to justify to the bottom or right of         the form.     -   4. Steps can be anchored to resize their width or height with         the form.     -   5. Forecolor, Backcolor, Read-Only status, enabled status, and         visible status can all be set for each step.     -   6. An infinite number of pages can be used     -   7. Graphical trim such as labels, lines, rectangles, group         boxes, and images can be placed on the page.     -   8. Multiple layouts for separate devices, including printing         layouts, may be kept together but authored separately.     -   9. Each page's background color and size ability can be set.     -   10. If the page is set not to resize with the client, scroll         bars may be automatically added at runtime to allow the user to         continue to use all pages.

In an embodiment of the present invention, a smart database design is utilized in addition to the previously mentioned aspects to allow for efficient utilization of database space and processing time. In this design, only primary keys are used as meta-data to construct many-to-many relationships between table, resulting in amore robust, efficient database structure. Once tables of user-specific data are bound to the database as meta-data using their primary keys, the system may automatically ensure the handling of the records as related units. This eliminates the traditional heavy-weight dependence on foreign key relationships.

In an embodiment of the present invention, an object oriented design presents data in the database as objects and attributes. Data may be stored in a relational database, but may be accessed via a database access engine. All objects, attributes, and object definitions may then be stored in the database. This meta data may be read and used by the database access engine to present the system to the user and programmer.

In an embodiment of the present invention, the meta data for an object may describe its name, display names, icon, system type, and security attributes. The meta data for an object attribute (field) may describe its data type and length, input mechanism, display name, list valid values, system type, and other data. The database access engine may also support a “system type” for the object and/or attribute which allows the user to define a private, public, or protected object or field. A private object attribute is never visible or editable. A public object/attribute is visible and editable. A protected object/attribute is visible but not editable.

All user defined objects in the system may contain preset system fields that allow them to be recognized by the database access engine as a proprietary object and allow it to be involved in the various object support functions supported by the database access engine (relationships for example). The preset system fields may include an identification (the primary key), creation date, last update, created by, last updated by, name, and deleted by. The database access engine may maintain these system fields automatically. A record in the relational database management system may represent an instance of an object—also called an item. Furthermore, in an embodiment of the present invention, no record is ever physically deleted, but rather they are just marked as deleted. Archive functions may be provided to physically remove the item.

In an embodiment of the present invention, many-to-many relationships allow for any type of relationship to be modeled with no understanding of database concepts or redundancy of data. This relationship is made possible by a central relationship table. In an embodiment of the present invention, the relationship table may contain the parent object, the parent instance identification, the child object, and the child instance identification. Additionally, there are no database enforced key constraints on this table, allowing new tables or permutations to be added without restriction. All operations to make, remove, and search on the relationships in the relationship table maybe performed using the database access engine, which exposes this functionality as a set of objects with properties and methods. The system then may automatically prevent duplicate relationships or circular relationships from being defined.

In an embodiment of the present invention, a point and click interface may be utilized to design the objects. Additionally, the object definition may be serialized/deserialized for distribution to other installations of the smart database or for saving to disk for archiving purposes. The database model may provide for multiple types of objects to be created. Since all objects are exposed via the database access engine, the underlying logic to an object does not have to be a one-to-one correspondence to the relational table that a typical system would use to contain the data. Because the database access engine potentially exposes all functionality in object-oriented terms, SQL is not necessary or expected. Furthermore, the database access engine may handle all database management system-specific syntax.

In an embodiment of the present invention, the database access engine caches intelligently on an as-requested basis. Meta data is cached, for example, to prevent undue stress on the database platform. Caching of this type of information is done to give automatic performance boosts without having to understand indexes.

FIG. 23 is a diagram illustrating meta data in accordance with an embodiment of the present invention. As described above, meta data may be stored using one or more object definitions 2300 along with linked attribute definitions 2302, and potentially list definitions 2304 as well. An object definition may describe meta data about an object, and may contain an identification 2306, a name (which is in actuality a table name) 2308, a display name 2310, a plural display name 2312, an icon 2314, a description 2316, a system type 2318, and security permissions 2320. The system type 2318 may be private, public, or protected. The distinctions between these terms is described in more detail above.

Each object definition 2300 has a link to one or more attribute definitions 2302. Each attribute definition 2302 may describe meta data about an attribute (or column) of the data, and may contain an identification 2322, a name (which is in actuality a column name) 2324, a display name 2326, a description 2328, a data type 2330, a data length 2332, an input mechanism 2334, a system type 2336, various system options 2338, and a list name 2340. If the attribute definition 2302 contains a list name 2340, then it is an indication that there is a list definition 2304 linked to attribute definition 2302.

A list definition 2304 may describe meta data about a list, and may contain a list name 2342, a display name 2344, and a database value 2346.

When a relationship between two or more objects is created, information regarding the relationship may be placed in a relationship table. Relationships between objects are commonly referred to as parent-child relationships. The relationship table 2348 may store, for each relationship, the parent object identification 2350, the parent object instance identification 2352, the child object identification 2354, and the child object instance identification 2356.

As discussed briefly above, duplicate relationships and circular references may be avoided using an embodiment of the present invention. FIG. 24 is a flow diagram illustrating a method for handling a new relationship in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 2400, the system may examine the relationship table to ensure that the same parent/child relationship doesn't exist. If the relationship does exist, the request has already been fulfilled. In one embodiment of the present invention, relationships that are deleted aren't actually removed from the relationship table, but are merely marked as “deleted”. If it is the case that the relationship to be added matches one that is in the relationship table but marked as deleted, the system may simply undelete the old relationship, thus reestablishing it. Thus, at 2402, it may be determined if the relationship in the relationship table has been marked as deleted. If so, then at 2404, it may be undeleted.

If the relationship does not exist in the relationship table, then at 2406, the system may determine recursively if any ancestors of the proposed parent match the proposed child. Since this is a recursive function, the system may first check parents of the proposed parent. Then it may check parents of parents of the proposed parent, and so on. In an embodiment of the present invention, the function may have a built in limit on the number of levels to recursively check (e.g., 10 levels), which will function as an upper limit on the number of levels to check, assuming the check hasn't run out of ancestors or a match has been found. If somewhere in this recursive check the proposed child was found to match an ancestor, at 2408 an error may be generated. If the check passes, however, then at 2410, the relationship may be established and placed in the relationship table.

When a user request that a relationship be broken, the system may simply label that relationship as deleted in the relationship table. The objects themselves may not be affected.

FIG. 25 is a flow diagram illustrating a method for inserting a new item of data into the database in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 2500, the system may insert a new record into the table, automatically setting the create_date and last_updated system fields to the current time on the server, the created_by and last_updated_by system fields to the identification of the user making the request, the deleted_by system field to −1 (not deleted), and the name field to whatever name the user has provided. At 2502, a unique identification may be automatically generated for the record and saved in the record.

FIG. 26 is a flow diagram illustrating a method for updating an item in a database in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 2600, the system may confirm that a change was actually made to the item. It may accomplish this by keeping the original values when the item is first loaded and comparing them to the current values. If no change was actually made, then at 2602 the update may be considered successful, even though no database operation is performed.

If a change was made, then at 2604 the system may confirm that the item exists in the database. This may be accomplished by comparing the unique identification of the item with the identifications of the item in the database. If it does not exist, then at 2606, the operation may be switched to an insert operation. This insert operation may differ from the insert operation described in FIG. 25 and the corresponding text by virtue of the fact that it does not need to generate a unique identification, as it already has one. The unique identification need only be saved. By switching to an insert operation, this ensures that records from separate databases can be easily replicated without having to worry about whether the item exists or not.

If a change has occurred and the item does exist in the database, then at 2608, the system may update the last_update field to the current time on the server and the last_updated_by system field to the identification of the user making the request. Then at 2610, the updates may be applied to the record.

FIG. 27 is a flow diagram illustrating a method for deleting an item from a server in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. At 2700, the system may update the last_update system field to the current time on the server, and the last_updated_by and deleted_by fields to the identification of the user making the request. Then, at 2702, any relationships that the item is involved in may also be marked as deleted in the relationship table.

It should be noted that in an embodiment of the present invention, “deletion” means that the system field of for deleted_by is marked with a valid user identification. If the deleted_by field is less than zero, the item may be considered not deleted. Additionally, in an embodiment of the present invention, if the user requests that an item be deleted from a client database, then the item may simply be physically deleted from the database. This is due to the fact that client databases are typically transitory and are limited in available disk space.

FIG. 28 is a flow diagram illustrating a method for storing data in a database in accordance with an embodiment of the present invention. Each act of this method may be performed by software, hardware, or any combination thereof. The data may contain ordinary data and meta data. At 2800, the meta data may be persisted into the database as two or more object definitions, each of the objected definitions linked to one or more attribute definitions. The attribute definitions may optionally be linked to list definitions. Each object definition may include an identification, a name (which is in actuality a table name), a display name, a plural display name, an icon, a description, a system type, and security permissions. The system type may be private, public, or protected. Each attribute definition may include an identification, a name (which is in actuality a column name), a display name, a description, a data type, a data length, an input mechanism, a system type, various system options, and a list name. If the attribute definition contains a list name, then it is an indication that there is a list definition linked to the attribute definition. At 2802, the ordinary data may be saved in the database as two or more instances of the two or more object definitions, each of the instances of object definitions linked to the one or more instances of attribute definitions. The instances of attribute definitions may optionally be linked to instances of list definitions. At 2804, a relationship between the two or more object definitions and the two or more instances of object definitions may be stored in a relationship table in the database. This may be accomplished by storing an identification of a parent object definition and an identification of a parent instance of the parent object definition in a relationship table along with an identification of a child object definition and an identification of a child instance of the child object definition.

FIG. 29 is a block diagram illustrating an apparatus for storing data in a database in accordance with an embodiment of the present invention. Each element of this apparatus may be embodied in software, hardware, or any combination thereof. The data may contain ordinary data and meta data. An object definition and attribute definition meta data persister 2900 may persist the meta data into the database as two or more object definitions, each of the objected definitions linked to one or more attribute definitions. The attribute definitions may optionally be linked to list definitions. Each object definition may include an identification, a name (which is in actuality a table name), a display name, a plural display name, an icon, a description, a system type, and security permissions. The system type may be private, public, or protected. Each attribute definition may include an identification, a name (which is in actuality a column name), a display name, a description, a data type, a data length, an input mechanism, a system type, various system options, and a list name. If the attribute definition contains a list name, then it is an indication that there is a list definition linked to the attribute definition. An object definition instance and attribute definition instance ordinary data saver 2902 may save the ordinary data in the database as two or more instances of the two or more object definitions, each of the instances of object definitions linked to the one or more instances of attribute definitions. The instances of attribute definitions may optionally be linked to instances of list definitions. An object definition and object definition instance relationship table storer 2904 coupled to the object definition and attribute definition meta data persister 2900 and to the object definition instance and attribute definition instance ordinary data saver 2902 may store a relationship between the two or more object definitions and the two or more instances of object definitions in a relationship table in the database. This may be accomplished by storing an identification of a parent object definition and an identification of a parent instance of the parent object definition in a relationship table along with an identification of a child object definition and an identification of a child instance of the child object definition.
